Perhaps you should try some spelling variations:
rent sharing » risk sharing, rent seeking
cost sharing » risk sharing, cost savings
anhang der » anhand der, anhang dr, anhang die
wang yin » wang yan, wang lin, wang qin
hang der » gang der, klang der, zwang der
minh hoa » mind how
hoa secs » how secs

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yin ((hang der) OR (anhang der)) ((rent sharing) OR (cost sharing)) minh hoa secs ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yin ((hang der) OR (anhang der)) ((rent sharing) or (cost sharing)) minh hoa secs ;~".
• Adding a wildcard symbol may retrieve word variants: wang yin ((hang der) OR (anhang der)) ((rent sharing) or (cost sharing)) minh hoa secs ;*.
